The controller uses industrial computer platform, dual CPU architecture, multi-layer circuit board processing, stable and reliable operation of 3 use large screen touch LCD all Chinese display, parameter display, setting and query convenient and intuitive. The adjustment is accurate, fast and adjustable, and can be adjusted in the full range of rated current of 0~ 100%. The high voltage earthing fault line selection module is built with the residual current increasing cocoon method and the active power method. With RS232, RS485 and IEC61850 communication interface, it can communicate with the host computer and achieve long-distance signal transmission. It can realize the function of sound and light control of single-phase grounding fault. Equipped with standard printer, data printing and grounding letter printing can be realized. With one control two functions, one controller can control two sets of arc suppression coils.
